PlLE-WIRE FOR LOOMS.

SPECIFICATION forming part of Letters Patent No. 665,577. dated January8, 1901.

Application filed December 5, 1899. Serial No. 739,276. (No model.)

To all whom it may concern:

Be it known that I, ALFRED F. MoOoLLUM, a citizen of the United States,and a resident of Espy, Pennsylvania, have invented certain Improvementsin Pile-Wires for Looms, of which the following is a specification.

The object of my invention is to so construct a pile-wire that the samecan be readily applied to or detached from the head with which such wireis usually provided in order that it may be properly moved andcontrolled by the mechanism of the loom.

In the accompanying drawings, Figure 1 is a side view of a portion of apile-wire with head secured thereto in accordance with my invention.Fig. 2 is a similar View showing the wire adjusted to a position whichwill permit it to be detached from the head. Fig. 3 is a perspectiveview of the head and of the end portion of the wire intended forengagement therewith. Fig. 4: is an enlarged transverse section on theline a; 00, Fig. 1. Fig. 5 is a side view illustrating the constructionof the head for the reception of a wire of U- shaped cross-section. Fig.6 is a View showing such a wire applied to the head. Fig. 7 is a Viewshowing the manner of releasing the wire from the head; and Fig. 8 is anenlarged section on the line y y, Fig. 6.

The pile-wire 1, which is shown in Figs. 1 to 4:, is a solid wire withshank 2, terminating in a hook 3; but my invention is applicable togrooved wires as well as to solid wires, as will be explainedhereinafter. The head 4 has upper and lower jaws 5 and 6 for thereception of the solid shank 2 of the pile-wire, the adjoining faces ofthese jaws being grooved, as shown in Fig. 4, so as to fit snugly tosaid solid shank. Inwardly beyond the grooved portions of the jaws is arecess 7, and into this recess projects from the upper jaw 5 a finger 8,which when the pile-wire has been fully inserted into' the head, asshown in Fig. 1, is adapted to engage with the hooked end 3 of saidpile-wire in order to retain the same longitudinally in position inrespect to the head.

In applying the head to the wire said head may be slipped over the endof the wire while the hook of the latter is uppermost and then hammeredlightly until the hook has passed inwardly beyond and into engagementwith the finger 8, the natural spring of the shank of the pile-wire, aswell as the spring of the jaws 5 and 6, permitting the relative movementof the parts necessary for this purpose.

When it is desired to detach the wire'from the head, the wire is turnedhalf-way around, as shown in Fig. 2, so as to carry the hook of the samedownward, and the head can then be withdrawn longitudinally from thewire and, if desired, the wire can be inserted by a reverse operation.

When the wire is grooved or U- shaped, the

recess 7 is preferably formed in the upper jaw of the head and thefinger 8 on the lower jaw, as shown in Figs. 5, 6, and 7, and the hookis formed on the under side of the wire, as also shown in said figures.hen it is desired to release the wire from the head, said hook may bepressed upward by means of a suitable implement until it is clear of thefinger 8, and the wire can then be withdrawn longitudinally. A recess 9,formed in the side of the jaw 6 just beyond the finger 8, facilitatesthe pressing upward of the hook. The upper jaw 5 is grooved on eachside, so as to form a central rib 10, which enters the groove of thewire and effectually prevents lateral displacement of the same.

Having thus described my invention, I claim and desire to secure byLetters Patentl. The combination of a pile-wire having a hooked end withthe head having a grooved portion for the reception of the pile-wire andinwardly beyond said grooved portion a recess with finger projectingthereinto for engagement with the hook of the wire, said recess being ofsuch size as to permit engagement and disengagement of the hook andfinger by movement of the wire, substantially as specified.

2. The combination of a pile-wire having a hooked end, with the headhaving upper and lower jaws, forming a groove for the reception of thepile-wire, and also having, inwardly beyond said jaws, a recess withfinger projecting thereinto, for engagement with the hooked end of thewire, said recess being of lo gagement and disengagement of the hook andfinger by movement of the Wire, substantially as specified.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing Witnesses.

ALFRED F. MOCOLLUM.
